API and Breaking Changes

New API Features and Deprecations since v1.3

Note all deprecations are soft deprecations, meaning that none of the deprecated options or attributes were removed from the runtime player. They will remain available for backwards compatibility until v2.0.

• Added config.workerPath to support loading of a hosted hls.worker.js script over worker injection
• xhrSetup can optionally return a Promise for async setup of XMLHttpRequest instances
• ERROR Event enhancements:
  • All ERROR events include an error property of type Error which references either a caught exception or an Error object instantiated at the point of failure with a friendly error message
  • Added errorAction property to ERROR events, used by error-controller to resolve errors through retries and adaptive switching
  • Added stats property to ERROR events, used to gather timing information from network errors
  • Marked ERROR event err deprecated (replaced by error)
• Added LEVEL_PARSING_ERROR to ErrorDetails, triggered when the playlist parser encounters invalid HLS content (Variable Substitution)
• Added FRAG_GAP to ErrorDetails triggered when encountering a Segment or Part with a GAP tag or attribute, instead of attempting to load the media marked as unavailable. Error handling will attempt to switch renditions or jump the gap if a suitable replacement is not found.
• Marked lowBufferWatchdogPeriod as deprecated (implementation missing/removed)
• Deprecated loading timeout and retry config options in favor of new LoadPolicy options
  • A warning is logged when configuring the player with the deprecated loading settings, as they are converted to the new load policy options.
